JOSIAH PEROIVAL STEVENS, OF ATLANTA, GEORGIA.

PLATE-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 764,158, dated July 5, 1904.

Application filed September 30,1903. Serial No. 175,221. (No model.)

To all whom it may concern:

Be it known that I, JOSIAH PERoIvAL' STE- VENS, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and use- My present invention relates to presses or machines for printing from engraved plates, and it is intended as an improvement upon the machine described in Letters Patent No. 649,773, granted to me May 15, 1900, and entitled Plate-printing machine.

According to my present invention the machine has or may have its power self-contained, and thus may be moved from place to place and operated in sit-u without reference to eX-. traneous sources of power. Furthermore, improved means for holding the plate in position are provided, as also for holding the card or sheet to be printed and for readily supplying and removing the same, also to protect the card or sheet from blurring.

It also consists in the improved means for automatically inking the plate and means for adjusting the several parts for use with cards or plates of different sizes.

My invention also consists of certain. novel features and constructions and arrangements of parts, which will be hereinafter described and claimed.

Reference is had to the accompanying drawings, in which the same parts are indicated by the same characters throughout the several views.

Figure 1 shows a side elevation of the complete machine. Fig. 2 is an end elevation as seen from that end of the machine carrying the card, at which stands the attendant, here-. inafter called the feeder. Fig. 3 is a plan view, partly in section, along the line 3 3 of Figs. 4 and 5. Fig. 3 is adetail showing an inverted perspective view of one of the adjustable plate-holders. Fig. 4 shows a section along the line 4 4 of Fig. 3 looking in the direction of the arrows. Fig. 5 showsasection along the line 5 5 of Fig. 3 and looking in the direction of the arrows. Figs. 6 and 7 are similar sections to that indicated in Fig. 4, but showing the printing-roller in different I positions from that indicated in Fig. 4. Fig.

8 is a plan view of the card-carrier detached from the machine. Fig. 9 is an end view of the device shown in Fig. 8 looking toward the top of the sheet. Fig. 10 is a detail showing the spreader-bar for the card-gripper.

Fig. 11 is a detail showing the means of adupper printing-roller.

A represents the frame of the machine, which may be of any suitable form, for supporting the several parts of the press, but which in the present instance is shown as consisting of two side frames connected together by the tie-bolts A and A These frames are provided with feet A and also with a vertical upper portion A and brackets A to Which the table B is secured, as by means of the tie-bolts A The upper vertical portion is provided with housings A and A in which are mounted the journal bearings for the shafts f and H, as will be hereinafter described.

The table B is preferably provided with vertical sides 6 and vertical ends 6, on which latter the posts B are secured, as by means of the clamping-screws b Spanning these posts B and extending the full length ofthe table are the guide-rods B on which the plateholder D and the card-holder E slide.

C (see Fig. 3) represents a pulley secured to the post B over which pulley passes the strap C, connected at one end to the weight (1 and at the other to the plate-carrier D, and thus .this weight tends to return the plate-carrier means for adjusting the operating-face of the which is mounted to slide along the rods B and at the endof its travel toward the operator engages the sleeve 5, (see Fig. 3,) which bears against the spring I), and thus the sleeve and spring act as a buffer to check the backward movement of the plate carrier. The bed-plate D is provided with sockets, in which the lugs (Z from the plate-holder D project. The plate-holder carries two fixed stops cl for holding one end of the plate and two adjustable stops (Z, projecting from the groove do in the plate-holder, (see Fig. 3,) for the other end of the plate. These stops (Z are adjusted by means of the screws D I provide a series of plate-holders of different sizes, so that plates of different sizes may be mounted on the same machine without excessive adjustment of the stops cl. seen that the plate-holder D may be readily removed and a larger or smaller put in place Without otherwise interfering with the action 3f the machine, and this may be very quickly one.

The means by which the plate-carrier and card-carrier are coupled together and the two are moved together during the operation of printing cards and then automatically released and restored to the initial position at each end of the machine can better be described after explaining other parts of the mechanism.

F represents the lower printing roller,

which is mounted on the shaft f, journaled in fixed bearings f at the lower end of the housings A. The upper printing-roller N is fixed on the shaft H, which shaft carries the clutch member H and spring H for throwing the same into engagement with the clutch mem ber G on the hub of the wheel G, which is mounted loose on the shaft H. This wheel G is at once the drive-wheel and fly-wheel of the machine, and it is driven by means of a belt M, which passes over idlers N 2 to the drivingpulley h/ 3 on the electric motor M. The connections for the electric motor not being a part of my invention are omitted from the 'drawings for the sake of clearness.

I preferably drive the machine by means of anelectric motor, so that it may be located in any convenient place in the factory and driven by feed-wires from any suitable source of current; but, if preferred, the wheel G may be driven by means of a belt from any line of shafting or by any suitable gearing. The wheel Gr is normally kept continuously in r0- tation while the machine is being used; but the shaft H-only turns with the wheel Gr when the clutch members H and G are in engagement. These clutch members are normally kept apart by means of the wedge K, which projects between the clutch members and is held up in position by means of the spring K mounted on the bracket K", fast'to the frame A. The rod. K passes through the spring K and is connected by the link K to the lever K, which lever is connected by the rod K to It will be the treadle L, which is pivoted to the frame, as at L, and, is provided with a shoe-piece L. Thus it will be seen that bypressing down on this shoe-piece the wedge K'is withdrawn, and the spring H throws the clutch members G and H into engagement and causes the shaft H to rotate with the wheel Gr. Any suitable clutch-operating mechanism maybe usedsuch, for instance, as that shown in my Patent No. 649,773, aforesaid.

The ends of the shaft H are journaled in journal-bearings it in the housing A These journal-bearings are pressed upward by the springs J and are adjusted downward by means of the screws I, projecting into sockets h on the upper member of the journal-bearing it, as shown in Fig. 1. By means of these screws the distance between the compressionsurfaces of the upper and lower printing-rollers may be adjusted to suit various thicknesses of plate. The upper printing-roller N is cut away on one side, as indicated in Figs. & to 6, and the cylindrical portion may be covered with several layers of paper it, held in place by the spring N, whose ends abut against the shoulders 91, and thus bind the paper in place, as described in my Patent No. 19,773; but the operating-face of the upper printing-roller is preferably constructed as shown in Figs. 14 to 17, in which N represents a block in the form of a segment of a cylinder and provided with flanges N and N, as shown in Fig. 16, over which flanges the hooks N engage. These hooks are pivoted in the roller N, fast on the shaft H. Pins N project from the roller N and engage in sockets n in the block N as shown in full lines in Fig. 17 and in dotted lines in Figs. 18 and 19. Over the face of the block N is mounted a plate 013, of brass or other suitable metal, whose ends are secured to the shoulders of the block, as at 12, Figs. 18 and '19. By having a series of these blocks 1 3 of different lengths circumferentially, the operating-face of the upper printing-roller may be adjusted to correspond to the size of the plate on the plateholder.

Three sizes of the block N are shown in Figs. 14., 18, and 19; but the number may be increased indefinitely. It will be seen that these blocks N may be readily and quickly applied to and removed from the roller N, and thus by shifting the plate-holder and the impression-block N on the upper roller the machine will be readily adjusted for any desired size of plate.

Loosely mounted on the shaft H is the oscillating ink-roller frame, which comprises the hub 0 from which projects two arms 0 and 0 set at an obtuse angle. The arm 0 carries the inking-roller 0, while the arm 0 is connected by the cord or strap 0", passing over the pulley O to the arm 0 operated by a coil-spring in the box 0 (See Figs. 1 and 5.) The tendency of this springcontrolled arm O is to hold the arm 0 in the position indicated in full lines in- Fig. 5, with the ink-roller O pressed against the ink-distributing roller P. The ink-roller O is preferably made of a series of rings or disks of Canton flannel or like material,as is well known in the art. This ink-distributing roller P is mounted on a shaft P, which carries a gearwheel P meshing with the pinion Q on the shaft Q, which shaft carries the gear wheel Q meshing with the pinion G on the hub of the wheel G. Thus the rotation of the wheel G will rotate the shaft P and will cause the roller P to rotate the ink-roller O. The ink T, in the ordinary pasty form, is held between the guards R in front of the board R, which carries a spreader R, adjusted by means of the straps 13 and screws 9*. Behind this spreader is the ink-distributing roller S, which preferably has a longitudinal as well as a rotary motion in the manner well known in the art and whichserves to evenly distribute the ink on the roller P.

The card-carrier E carries the downwardlyprojecting arm 1, to which is attached the cord U, which passes over the pulley U, mounted in a hanger U secured to one of the rods B This cord U is connected to an arm U which is normally under stress from the coil-spring in the box U5 (See Fig. 2.) The tendency of this spring is to draw thecard-carriageto ward the plate-carriage, and when this spring is allowed to act the coupling 2 on the cardcarriage snaps over the hook cZon the platecarrier, and the two are coupled together.- The card-carrier is held in the initial position at the feeders end of the machine by means of the stop c on the spring-catchV, which is normally pressed upward, as shown in Fig. 4:, by means of the spring V. This. spring-catch is drawn down by the cord V when itis desired to release thecard-carrier, and the latter is then impelled by means of the cord U* toward the plate-carrier. This cord V is connected to the lever V, which is sus, V

pended, as at V*, from one of the tie-bolts A and this lever is connected by means of the rod V to the treadle NV, which is pivoted, as at WV, to the treadle L. This treadle has a lug V which projects through a hole in the shoe L of the treadle L, so that the pressure of the foot of the operator will cause the treadle VVto pull down the rod V and release the card-carrier before the treadle L, withdrawing the wedge K from betweenthe members G and H of the coupling on the shaft H. The hook (Z is on a spring-plate D", secured to the card-carrier, as by screws D", (see Figs. 4, 6, and 7,) and the forward end of this plate is curved, as at (Z to strike the pin X and withdraw the hook B* from engagement with the coupling 2 of the card-carrier when the plate-carrier has reached the limit of its travel. (See Fig. 7.) At this time the card-carrier is held by the arm l engaging the catch '0, while the plate-carrier is free to return to the initial position under the action of the weight C When the card-carrier is coupled to the plate-carrier, the card or sheet to be printed will be in the proper position over the plate and will be moved to the right between the in Figs. 4, 6, and 7. When the parts are in the initial position, (shown in Fig. 4,) suppose the operator presses with his foot on the shoe L the first motion of his foot will press down the the stud. W releasing the card-carrier and allowing it to fly over to and'couple with the plate-carrier. A further motion of the foot will press the shoe L down, removing the wedge K from the coupling and transmitting the motion of the wheel G to the shaft Hand to the printing-roller N fast thereon.

As the-printing-roller revolves the roller Y will engage the lug D pushing the two cari riages,which are coupled together, to the right against the action of the weight 0 Before the roller Y passes clear of the boss D the plate D and the plate-holder D, with the bed supporting the same, are firmly gripped between the surfaces of the upper and lower printing-rollers, and the plate-carrier is pushed on through until the rotation of the upper printing-roller N causes the rounded surface to pass clear of the plate, as indicated in Fig. 7 At this time the plate-carrier is automaticallyuncoupled from the card-carrier, as before described, and the plate-carrier returns to its initial position under the action of the weight C, while the card-carrier is held in the initial position by the catch 1).

During the cycle of operations just 'described th'e inking mechanism is put into action, as will now be explained. When the card-carrier and the plate-carrier are in the,

initial or separated position, as shown in Fig. 5, the ink-roller 0 will be up against the distributing-roller P and the arm 0 will project downward in the position indicated by the full lines in Fig. 5. carrier is started from the initial position in the manner hereinbefore described the roller D which is fast to a plate D adjustably connected to a side of the plate-carrier, en-;

gages the upper face of the arm 0 and rolls along the same, at the same time rocking the hub 0 about the shaft H. Before the platecarrier ,will reach the limit of its travel the ink-roller will be rocked down to the position indicated in dotted lines in Fig. 5, until finally the stud 0* on the arm 0 will pass in ;front of the catch Z on the spring-bar Z,

Soon after the plate-- which is adjustably connected, as by means of the screws 2 and .2, to the table B. This catch Z will spring up in front of the stud O" and will lock the arm in the position indicated by the dotted lines in Fig. until the plate-carriage returns almost to the initial position. Just before the plate reaches the initial position the curved end b of the bar D", which is secured to the plate-carrier, as shown in Fig. 5, will ride up over the curved end Z of the spring-bar Z and will press the catch Z out of engagement with the roller 0, allowing the cord 0 to swing the inkingroller back to the initial position. (Shown in full lines in Fig. 5.)

The manner of inserting and removing the card or sheet to be printed from the card-carrier and of operating the card-carrier will now be described. 1

In the initial position the card-carrier will be at the end of the machine next the feeder, as shown in Figs. 1, 3, 1, and 5, with the catch 4) engaging the arm 1, holding the carrier against the action of the cord U, as indicated in Fig. 4E.

The card-carrier consists, essentially, of twomembers a bed and a card-gripper pivoted on said bed, with means for swinging said cardgripper laterally about its pivot and means for moving the card-gripper transversely, whereby the card-gripper may be accurately adjusted to receive the card and to hold it in the proper position and to carry it above the plate when the card-carrier is released.

The bed of the card-carrier is provided with two arms E and E with downwardly-projecting flanges 7 and 7", which flanges are perforated to pass over one of the guide-rods B Near the extremities of the arms E and E are feet a, which slide over the other guide-rod B so that the carriage slides freely on the two guide-rods B.

The card-gripper is mounted on an L-shaped frame E, which is pivoted on the pin 6 which pin slides in the slotin the bed of the carriage, (shown in dotted lines in Fig. 8,) and the said pin is transversely perforated to receive the screw-thread e, which is turned by the milled head a and is provided with a ratchet a and a spring-pawl 0 so that the screw 0 may be held in the desired position without turning when the carriage is vibrated backward and forward in the ordinary operation of printing. This screw 0 provides atransverse adjustment for the gripper relative to the carriage, while the gripper may be turned through a small angle by means a similar screw a, passing through a pin 0 projecting through the slot 6 in the arm E which screw is locked fast by the ratchet and spring-pawl e".

For convenience of reference I have indicated all the parts for giving transverse adjustment to the gripper by E and all the parts for swinging the gripper through a small angle by F".

The coupler-head 2 is mounted on a rod 3, which is adjusted by means of the milled head 4:, fast thereon, and the screw-threads 5, which mesh in the nut 6, fast to or integral with the flange 7 (See Fig. 9.) This rod 3 may be held against turning in any convenient Way, as by means of a bent pin 9 passing through one of the holes 8 provided in the rod and connected at its upper end to the bed of the carrier.

E represents a sliding spreader-bar having two wedge-faces 11 and 12 on its lower side, a notch 14 on its upper side, and a bent arm 13, with a flat upper face 15, as shown in detail in Fig. 10. This spreader-bar passes under two spring-gripping plates E, which are riveted to one arm of the gripper-frame, as at 18. The stem 17 of these gripper-plates is resilient, While the holding parts are broad, as at 16, so as not to disfigure the card. These plates are riveted to the bar 19, as shown in Fig. 13, and project over the inclined cardholding recess'21 in the bar 20.

The bars 19 and 20 are connected by the cross-pieces 22, and the spreader-bar E slides above the cross-pieces 22 in the slot between the bars 19 and 20. The spring E tends to withdraw the spreader-bar E; but the latter is normally held by means of the spring-catch E. This catch E (shown in detail in Fig. 12) carries a lip 23, under which the tripper E engages. This tripper is pivoted at 25 to the gripper-frame and terminates in abutton 26, which is so spaced that it may be struck by the wrist of the feeder when she has inserted the card. As soon as she has inserted the card she presses on this button 26, which causes the spring E to retract the spreader E, and the click of the parts gives a signal to the operator that all is ready at the feeders end for the machine to be started.

The gripper-bar is automatically operated, when the card-carrier nears the limit of its forward travel, by means of the bar 13, which is fast to the table B and strikes the arm 13 of the spreader-bar E just before the cardcarrier reaches the extreme limit of its forward travel, being pressed forward by the action of the printing-rollers. As soon as the upper printing-roller revolves clear of thecard the weight C pulls the two carriages still coupled together backward; but after the card-carrier has moved a short distance backward it is automatically uncoupled from the plate-carrier, as before described, and is locked in the initial position. This short back travel of the card-carrier affords play enough for the arm 13 of the spreader-bar E, so that when the bar is released the spring E can retract it far enough before it strikes the end of the bar. B to withdraw the wedges from beneath the gripping-plates E allowing the'parts 16 of these plates to spring down over and to hold the edge of the card, as shown in Fig. 13.

By having the groove 21 in the bar 20. in-

clined, as shown in Fig. 13, the stiffness of the card E or of the sheet of paper to be printed will cause the card or sheet to tilt up, as shown in Fig..13, and thus the card slides above the plate when the two carriages come together, and the resiliency of the card or .sheet causes it to spring up again after the printing-roller has passed over it, thus allowing the plate to be withdrawn from under the still moist ink adhering to the card without smearing. This is especially important not only in securing better work, but also in saving the time required to pick up the cards from the plate without smearing.

I have shown two bars 19 and 20; but it will be obvious that a single bar with a slot in the center may be used instead of the two bars, if desired.

It will be seen that nearly all the parts are made adjustable to provide for the exceedingly nice and accurate work required of a machine of this character; but many of these adjustments may be omitted, and the adjusting means may be varied at will.

Having thus described the coaction and operation of the several parts, I will state briefly the operation of the entire machine.

Suppose the wheel G to be running, but the shaft Hto be still and the card-carrier and the plate-carrier to be in the initial position.

(Indicated in Fig. 3.) WV hen the operator.

presses down on the shoe L the pressure on the stud l/V will release the card-carrier, which will fly forward and automatically couple to the plate-carrier; but at the first operation of the series there need be no card in the carrier, as the plate will not be inked. A further ,downward pressure of. the foot of the operneath the said printing-roller, and it will be pushed on through between the upper and lower printing-rollers, as before described. At the same time the ink-roller 0 will be brought down to the position indicated by dotted lines in Fig. 5. As soon as the upper roller N revolves clear of the plate the platecarrier will be drawn back by the weight C leaving "the card-carrier behind, as already describedv The plate will pass under the inking-r0ller and will be inked thereby, and after passing under the said rollerthe arm 0 will be released, allowing the cord O with the spring for operating the same, to swing the ink-roller O back to the position indicated by full lines in Fig. 5. The back travel of the plate-carrier will be limited, by the buffer 6 while the card-carrier will be held by the catch 0. The card-carrier will be pushed far enough forward in the machine to cause the bar B to press on the arm 13 of the spreader: bar E,

This will turn the print another one.

causing the wedges 11 and 12 to spread the gripper open for the reception of the edge of a card, this against the action of the spring E The spreader-bar is held in this position by means of the spring-catch E While the operator at his end of the machine gets the plate ready, the feeder at her end of the m a chine is inserting the card in the gripper. As soon as the card is in place she presses, preferably with her wrist, on the button 26, which releases the spring-catch E and allows the spring E to pull the gripper-bar F. back, causing the gripping-plates E to grip the card, as shown in Fig. 13. The'operator hears the click caused by the motion of the spreaderbar E and knows that the card or sheet is in place for printing. As soon as he hears this click, which will be about the same time he will have the plate ready, he presses on the treadles, as before, with the result that the treadle WV first releases the card-carrier and allows it to fly back and couple onto the plate carrier, while immediately thereafter the trcadle L withdraws the wedge K and allows the wheel Gto rotate the upper printing-roller N through a single revolution. The card now being over the plate and the latter inked is duly printed when it passes between the two printing-rollers, and after being clear of the upper rollerN the resiliency of the card causes it to tilt up slightly, as indicated in Fig. 13,- thus raising its inked surface clear of the face of the plate. The final forward movement of the two carriages coupled together will cause the spreader-bar to spread the grippers and the attendant takes the card out. Just as the grippers are spread the plate-carrier is automatically uncoupled from the card-carrier and is drawn backward by the weight C and the feeder removes the card and substitutes The cycle of operations may be repeated indefinitely. By having removable plate-holders of different sizes the plates may be readily fitted on the machine, whether for printing cards or sheets, and the card-carrier is also provided. with adjustments for readily, adjusting the parts to the required conditions.

It will be obvious that various modifications mightbe. made in the herein-described apparatus which could be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
